H I The mounting of the equipment frame uponthe tractor and wheelsubstitute.

4. The spool and drive assemblies of the winch unit.

5. The control system of the Winch unit.

Each of these assemblies 'will be described in detail andthe individualfunctions there of poi'n'teclient,after which their conj oint operationswill beset forth. The tractor 10 is usually eipiipped with front wheelswhich are steered in "the travel of the tractor and with rear tractiv'ewheel's moiinte'd upon the endsofthe housing; 11 of the ma a-a1 gear. Tomake traction more effective "Wheel substitutesareenfployed 'in lieupi-fthe wheels, sometimes taking the place of but "two Wheels and at othertimes taking the place of the four. In the illustration on the drawingafull crawler type of wheel :substitii't'e takes the place of the fourWheels. In lieu of the front axle of the tractor heavy beam 12'isemployed on which tlie central portion 13 of the front of the tractorrests and on which said front end of the tractor has limited swinmovement. It is ndtunusa-al to cushion the front end of the tractor onthis beam by means of springs 14 or of rubber blocks. It

' will be appreciated that in the movement of the tractor from place toplace it is desirable retake the jewel travel in this wa At'th'e ends ofthe beam the'front portion of side frames 15 of the crawler (not shown)are attached. The rear ortions of these side 7 frames 'aie s'ecured 'tothe axle housinn-atthe place Where the wheels are usually mounted.

t will be appreciated that the drive of the crawler is througlithe axlesof the tractor extending through the axle housings from the differentialand that the driving sprockets-16 have teeth 17 which engage With'lugs18 011- track shoes 19, which are hingedl'y connected in a series toform an endless track 20, drivenby the sprocketslfi. The side frames arealso providedwith guide wheels 21 runningon the under face of the track'and supporting the tractor on said track. The side frames also have theguide 1 sprockets 22 mounted therein by means of which the track isturned atth'e front of the machine.

These fpaits are well known in theart and constitute a tractorquite'difierent from the ordinary four Wheel farm tractor int-hat it isa machine 6f considerably mor weight, great er tractive POWQIg-fljlldcontrolled in a quite different finanner Theguidingfis done by employingbrakes-on the rear-sprockets and these brakes are appliedthroug'h themedium my r semangle 26.

rear thereof, 'it is necessary in a tractor equipped in the manner justdescri'bed to ap- -ply the excess Weight at the front as it is the 7forward portion or toe of the endless track that first engages the"ground inthe 't'ra'ifel of the track and is therefore the part whichshould have the Weight in order to make the contactsufficiently secureto produce the best results.

The mounting, therefore, of a piece of equipment on such a tractorshould be, as.

far as is praoticable 'on the front, although the underlying principle fof some of the features of this invention-1n ht be employed in rear endequipment, especially when the.

half tracks 'orsubstitutes for the rear wheels support the equipment onthe tractor there has been -provided side frames 23 and 24 ma'dei ofcast steel and suitably at their middle portions to 'proyidethenecessary strength. Lowercross "a'ngle 25 and "upper cross "angle 26 anda frontchanne1'27 are provided; for the purpose of "bracingfthe two sideframes'inspaced relationship, whilea bridgebrace28consistingof alfoiigdiagon- 30 and BOeandJcentral plate 31 are utilized to "stiffen the baseof the winclrfra'nie. It

The side frames are extended rearwar'd'ly and the "extensionisindicat'ed by the numeral 34 attlie lower end of which a plate 35 isplacec'lfor the purpose of permitting the side frames to rest upon thebeam 12. The upper portion 'offthis' extension is curved gracefullyforward and upward to'the cross a In the side frames in verticalalignment are :mOUIlte d the upper spool bearings36, lower'spoolbearings 37 and dri've'shaft beara a1 member 29, 'twc shortdiagonal'members ing '38. These bearings are provided "rfiifth covers toprotect them, as is usual. The

frame sides are also provided with bearing apertures in which aremounted brake fco'ntrol shaftsand a sliding gear control shaft. On theframe 23 areexten'sions to'the bearing blocks 36 and 37,jtapped-bosses39,7 by means of which supporting legs4Oareat- 'tach'ed by machinescrews, and these legs support a curved guard 41 encircling more thanhalf of'the periphery'of the large driven sprocket 42 of the Winch, Achain guard 43 for a portion'of'the upper reach inay be supported byastrap 44 from-a braee {rod to be hereinafter referred to. H a 1 Totherear of the harneI-YQT is attached the pinion guards 45 made of a singlepiece of material "and protecting about founfifths ,of the circumference'of'thedrive pinions.

asto present a tapped opening 48 for the attachment of a brace rod 49extending forwardly to theupper end of the winch frame;

this brace rod hasa-turn buckle 50 therein.

It will be appreciated that these clampsiand brace rod-are duplicated onthe-opposite side of the machine;

' The winchunit-is attached 'tofthe combined tractor and wheelsubstitute-by supporting the shouldered portion 51 ofth'eframe upon thebeam 12 and tying it thereto by the vertij 'cally disposed bolts 52 andthe horizontally P disposed bolts 53; The upper portion of the frame istied to the axle housing by means of thefbrace rod 49 which is-attachedair-54 to the frame; in fact the end of the brace frod passes throughthe members of. the frame andis utilized in *placeof a bolt if that-isfound" desirable. The supporting of the frame upon the beam l2 placestheweight of thissubstantial'piece oftracto-r equipment upon that partwhichisdesigned to carry such weights and not upon aportion of thetractor which is not so designed. "Itwill be appreciated-however thatthe tractor power plant itself rests upon this beam 12 and has which iscontrolledor supported by any suitable cushioning means'assprings orrubber blocks. It will be appreciated that the-use of the rods 49 tyingthe upper portion of the v winch frame to the rear of the tractor, whichhas not the same relative movement with respect to the beam'that thefront part of the tractor has, will enable the" power plant-to swingthis limited extent without interfering sufficiently flexible toaccomplish thisresult? The mounting of the unit upon. a rigid partof-thewheelsubstitute and tying it to the rear of the'tractor in such away to permit the'us'ual swinging movement between: the l J front oftractor and supporting beam," is of 7 itself a substantial advance intractor equipment. To} this feature, howeveiy is added means formakingsteady or rigid the tractor power plant with the wheel substitute andthe winch'unit, when the tractor is'brought to rest for the'purpose ofusing the winch. This means is made up of parts which are standard in afront end mounting for tractorequipment, the subj ect. of a companionapplieationfor-patent filed in the name ofFrank 'L.

Adjusting; rods 57" pass through theopenings in the horizontal leg of the angle 56' andthrough alignedopenings in the lower port-ionof the winch frame and the; crossangle 25.These rods are mounted so that they will be supported at their lower endwhere the nuts '58 and 59 lock the rod to thewinch frame. A lock nut 60,which may be reached through an opening.

in' theside frames of the winch, will enable one totie the winch fra-meto the-tractor power plant by tightening up this nut against Y the upperface of the angle 56. 8 Since the s frame is*alreadylirigidly connectedto the beam 12 it follows ;that the tighteningr of these lock nutsr60will also rigidly tiethe;

F or .the purposehowever of being sure that the nuts'60 do not fallfrom the end of therod fir', "said end is upset or otherwise formed to prefvent this.a'slight swinging movement on said beam i 'lhe spools 62and1 63 aremounted with their bearings'in vertical alignmentand be-- tween them isthe winch driveshaft 64. o The spools are formed of shanks 65 welded tosteel disks 66 :67, 68 and 69. 'Allyof these parts are mounted uponspool shaftsi'O and 71 and are spaced 'from'thebearings by means 7and74. JIt will be appreciated that the drum onifone spool corresponds'inaposition with the gear on thecompanionnspool; and thisis; forapurpose tobe hereinafter described. 7 v The brake drums haveattached tothem i lugs 75' on tlieiriinner. faces with which a holding pawl 76coeolperates to hold the spool in position, and this holding pawlhas aheel 77' which islactuatednby a tripper-78; 'The winch frame is providedwithsuitable means" for pivotally supporting the pawliand the, I ltripper. For this purpose a: lug 9 projects o forwardly from:..the upperportionaof the frame and at'its' end is provided with. a;

bearing. for any suitablepintle or the like, 80, for'the tripperaf Theweb of thewinch frame 'is'also provided at 81 with a bearing 1 iaperture, by means of which'the pawl-may be pivoted. The partsjust-described are quite analogous to the pawleassemblyywhich is the.subjectmatter of: anj-applicationfor patent by Frank L. 11 011113,filed Dec. 9,1927, '1 o and serially wnumbeied 238,841, towhicl ap iiiplication'refere'nce is now made for a more compiete disclosure 'of thiselement.

In order that the lower spool shown in Fig. 2 may likewisebe controlledby "a pawl, it is necessary to provide the disk 68 with a lug ring andthis may be attached by welding e t a point within the line ofattachment of t'he ring gear to this disk. I prefer to make thisseparate rather than making it a part of the ring-gear because the ringgear of this winch unit is the same as the ring gear of other winchunits which may be considered as companion equipment; otherwise the ringgear may befori'ned to provide these lugs. It will be noticed that boththe upper and the lower spools are provided with this lug ring." This isdone so that these spools may be reversed in position at anytime thatthe user may-desire it. In order to accommodate 7 the pawl 76 and thetripper '78 to a spool equipped with a hig'ringyit is necessary onlythat theattaching lug 83 for the pin-tle'of "the pawl and tripper shallbe made to conform to the smaller diameter of the lug circle, as

will be clearly apparent from a glance at the lower portionof Fig. 2.

Mounted horizontal ali gnnient with the drive "shaftte areo'scil'latingrods8 i and 85.

These are hearings in the side frame andextended and'bent to form thehandles 86 and The winch spools described obtain their power fromthesnlall sprocketfilover which passes the drive chain 88 which impartsits power to the large sprocket 42. The sprocket is moiinted on a hub 89secured in any suitable manner 'to the shaft "64:. This shaft '64 has'slidably niou'ritedon it'the cornpanic'n' pinions 90 {end 91, providedwith the usual keyw'av's co-acting with a 'ke'y on the shaft Yokes 92and93 movable with the couplings "9i andengage the pinions and causethenito be moved 'into' and out of mesh with the spool gears. It will beappreciated hatthe pinion 90 will mesh with the gear 73 andthe pinion 91wi-th the gear 74 when they are slipped to the limit oftheir"Inove'Inenttoward the "adjacent frame members. While in'th'e position shown in Fig.4 these "pinions 'aie encircled by the guards 45.

To accomplishthesliding?movementofthe pinions'on the shaft 6 1 thecouplings 94 and 95 are 'slidable'on the rod' 8%, and for this purposethey have :proj ectin-g from them connectors '96 and 971 which engagerespectively links'98and 99, which in turn are connected to levers and101. Itjwill be-appreciated that upon amovemeiit of these levers thelink will cause the connector, coupling andy'oke' to be moved withit-and thereby chest a'sliding of the pinion.

The ineanswhere'by thelevers "100 and 101 are mounted and operated willbeunderstood from a clescriptionof Fig.0 wherein the frame member 2 1 isshown as supporting up-' per and lower sleeves 102 and103 means of bolts1-0 1 and 105 passing through apertured bosses 106 and 107 andhavi-ngvtheir heads welded to the sleeves 1-02 and 108.

' In-the aligned openings the sleeves 102 I and 103. is mounted a shaftor rod 108 which is bent Eat its upper end into a handle 109 and at itslower end has fixedly secured th'e'lever 1501.; Between the sleeves 102and 103 there is mounted on this shaft 108 a'lon-g s-lee've 11=0 towhich is welded or otherwise suitably secured a second shift handle 111and also the lever .100. It will be appreciated that thetwo-shifthandles109 and 111 may be op erated v'sep'arately and that as aconsequence the pinion 90 maybe operated without affecting the 1pi'nion91, and likewise the pinion ill niay-be'operated without affectingthegpinion 90. It will be also obvious upon a study of thjeflrlelativeposition of two levers that they inightbe'joined together as by asuitable "cl-amp.whichwill position them :in vertical alignment, inwhich case theyfilnay be 0perat'ed in unison whereby when the pinion 90is infmes'h with it's'spool gear the pinion- 91. will-beout 'of niesh;likewise when the pinion 91 is in mesh the pinion 90 willrbe out ofmesh. The purpose-of this construction is to provide in a single doubledrhrn winch the :capability'of either individual control of'thespools'or unitary "control, as where a drag line operation is desired.The levers109 :and 111 are positionedat an elevation with respect to thetractor whereby they will be handyto the operator, and theyiare so;p0s1- v 2:

in proper adjustment. Itwill be appreciated that this adjustment'may bealtered at pleasv ure'by simply manipulatingthe lock nuts 120 intheusual manner. I i i From this description of thebrake and its mode ofoperation'it-will'be readily understood how .an operator standing tojthe'side of the machine may apply the brake to either one or the otherof the drums 'by selecting the handle 86 or 87 for manipulation.

To control the supply of fuel to the engine from a point at the side ofthe winch there is provided a control rod 121 whichis shown with'aturn-buckle 122 therein, although it will be-unde'rstood that a; turnbuckleis not necessary. The forward end of this rod is bent at 123'andpasses "through a supporting eye 124 mounted on'the side frame 24 in theusual manner. A terminal loop 125 for the easy manipulation is provided.The rear end of the rod'l22 is attached in a suitable manner'to a bellcrank 126 which in turn .is supported on a stub shaft'127 attached toasleeve '128Qfixedly supported on the brace rod'129. From the bellcrank126 a link; or rod-extends to the tractor gas control on the"opposite side of the machine and indicated by the-numeral 130 in Fig. 1fIt'will be appreciated that'by 'thisextension gas control the operatorofthe winch may supply'thenee- .essary fuel for fast or slow operationas needs demand-f An extension clutch control is provided and; comprisesa pedal13l which is a bent crank end of a transverse rod mounted in the'side frames of the Winch. A t the opposite side of the machine this redcarries alever arm 132, which in turn is connected to a bell "crank 133by the link 134,. the bell crank 133 of equipment'tooheavy to be carriedby the is pivoted at 135 to the differential housing and carries'the arm136 which is employed tosupport the hook 137 engaging over the end 138of the tractor clutchcont'r'olj It will be-appreciatedthat upon :adepression'of the pedal 131the transverserod will cause the link 134 tobeshifted ba'ckwards'and thisin turnj throughthe bell crank133 willcause the clutch pedal to be depressed and relieve the application ofpower to the small sprocket 61. i

' From-the foregoing description the operation of the individual partsof the mechanism will be apparent.v It remains onlyto co pletethe'disclosure to recitethe conjoint "operation' fi .When the tractor isequipped" with a; piece tractor itself there is added to theeo'mbination acarrying device for both the-tractor and the piece ofequipment. This carrying device is in the nature of a substitute for thetractor wheels. 1 Itmay be the base of a small locomotive or itmay takeany form that will give stability to the combination as a whole. In thepresent instance "is shown a full crawler type of base which changesthecharacteristics of the four-wheel tractor "into one having endlesstracksi With such a carrying base the size and weight of the equipmentused with the tractor may be' 'increa'sed as provision is made forsupportinggreater weights sustaining greater strains. 'Itwill be notedin the pres.

entillustration' that the beam '12 isutilized 1 tosupport the doubledrum, winch and that said; beam also supports the forward'portion of thetractor power plant.- The upper portlOIlIOf the winch fraineiis tied to,or braced from the "axle housing of] the tractor and there is an'intermediateconnection between the tractor and, the winchframeconsisting of the shelf 56 secured to the tractor casting 55 andthe bolts 57 which are passed through the lower portion-of the winchframe. When the nuts 60 are tightened Yup the tractor "power plant issecuredftothe winch frame.

The importance of this mounting is the securing" of greater steadinessin thecompleted structure, while the parts are still capable of easydisassemblage. They are neverthelessv firmlysecured together, thetractor power 'plant is secured to boththe winch frame and the 'beam'12,the winch frame is secured to the beam 12 and also to the rear of thetractor, while the tractor itself is secured to other parts of thecrawler attachment as will be appreciated. This construction makes for asecure and'ste'ady' mounting of tractor and equipment upon thesubstituted base and enables-a larger piece and a heavier piece ofequipment to be used with the tractor. It is substantially removing thetractor 3 asv a mountfor the equipment and utilizing the connection ofthe winchframe to, both the ifront and/rear of the tractor as steadyingniearisfor the tractor upon the supplemented base, that isimportant.

E 1 While the mounting of this kind is in itself a substantialimprovement over ordinary inounts it has in the present lnstance aspecial application. Itiwill'be appreciated that the tractor, whenmounted upon one. of the wheel substitutebases referred to; retains acertain ability to: oscillate upon that base. And this is desirableinrorder that shocks and strains thiewihe; I creme ifh base sh not betoo sharply'imparted to the'p'ower plant of the tractor. It is notunusual tocushion a rewrpl nt and n F u e of e d a means for; us ion ng?is .s onnii t Spri s l4. and: t e ".eenne iees th rse t th baseWhen'howevena piece-of equipment tobe-used it is desirable tohave italways ready for driving from the tractor power plant and also desirableto have it steady with respect to the power plant in order thatvibrations of the engine shall not jar the parts excessively.Theretoreprovision must be made torpernrittnig the power plant to osillate with respect to the rest of the combine ion and also forthe tyingup ofthepower plant and the equipment in. a rigid manner when theequipment is to be used. The use of the equipment is usually desiredwhen the tractor is at a standstill although with some forms ofequipment this may not be true. It is true in connection with the winchshown in this application. I r V It will. be. appreciated theretore thatthe present mounting is especially designed to satisfy the requirementsset forth for equip.- ment o-r". tl1-is kind. firmly supported upQnthe'beam lfland is carried with said beam from plac'eto- Place. Theloose connection, between thecasting and the winch. train-e as Well as.the tie con :ieetion tron-r the upper portion of the winch frame to theaxle housing will permit the power plant to oscillate whenever it, isdesirable for itto do so, Upon simply tight.- ening the nuts it ispossible to! tie the power plant and the winch in a fined or rigidrelationship and this is accomplished for the purpose of using theequipment.

Another feature of the device herein described isits compactness forpurposes of hipment. It will be noticed that no long attaching, beamsextending the length of the tractor are required. It will be furthernoticed that the frame is. simply extended to provide a shouldered orheeled portion to set upon the beam 12 and that the extension controlsand-tie rods, and other parts are divided so that no long lengths ofparts are necessary. It adapts itself; to easy crating. Furthermore,many of the parts employed are stock structural parts enablingreplacementthereof to be made when breakage occurs. Many of the partsare also designed to be sub stituted for similar parts in a line ofequip- .mont for tractors. For instance, the clamps l6 and 4:7 arecapable of being revolved so that they might be utilized in the mountingof a rv sn winch The d t?! may b utilized in mounting for a frontendsingle dr m ch who s tr e of h cast g and the he 56- The inch pa s, u
